CALENDAR.

SPECIFICATION forming part of Letters Patent No. 788,746, dated May 2,1905.

Application filed November 23, 1900. Renewed January 16, 1905. SerialNo. 241,350.

To (I/ZZ whom it nmy concern.-

Be it known that 1, WILLIAM ZAEHRINGER, a citizen of the United States,residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented a new and useful Improvement in Calendars, ofwhich the following is a specification.

The object of my invention is, first, to provide a calendar composed ofand printed on twelve sheets of paper and employing an index-handpivoted at their centers, adapted to point out successively-in a(LODSPiC-UOHS manner the day of the current month and the day of theweek simultaneously; second, a series of twelve calendar-sheets eachshowing the varying number of days in each month, the serial number ofeach month, the age of the year in number of days up to the end of eachmonth, and the months composing the four seasons of the year; third, aseries of twelve calendar-sheets each showing conspicuously the currentyear, month, and its serial numher, and, fourth, a series of twelvecalendarsheets each containing the dates of all Sundays in the yearapportioned to each month. These objects are attained with uncommonfacility, owing to the novel and peculiar manner of grouping the figuresand letters necessarily employed. All items of information are conveyedat a glance and are comprehensive, as will be evident when reference ishad to the annexed drawings, forming part of this specification.

Figure 1 represents the month of January of the year 1901, to be printedon a sheet oi paper, and will serve as a sample-sheet of the calendar.The eleven remaining months are not shown, as they are in most partsduplicates ot' the January sheet, and the differences in theircomposition, as hereimexplained, will be readily understood. Fig. 2 is avertical central section of the calendar shown in Fig. 1.

Obviously in composing this calendar the size of the sheets and thestyle of type to be employed are optional. I shall therefore assume thatthe dimensions of a sheet are eight by eight inches. in which case Iprefer that the apportionment of the spaces for the various items ofinformation to be printed willbe as follows: A circular central space Ais two and one-half inches in diameter to contain the name January,abbrevlated to Jan. in

large type, and the figure 1 above and the fi ures 1901 below the month,as shown in a I a I u A clrcular s )ace B, ad oinin the een- Fig. 1.tral space A and separated by two parallel lines, having a maximumdiameter of three and one-eighth inches, is divided into four equalparts, each part to contain the names of the respective seasons Spring,Summer, Autumn, Winter, as shown in Fig. 1. A circular space (I,adjoining the space E and separated by one line, having a maximumdiameter of three and iive-eighths inches, is divided into twelve eq ualparts, each part to contain the age of the year in days up to andinclusive of the last day of each month as they are successivel y namedin the next adjoining space, thus, 31, 59, 90, .120, 151, 181, 212, 243,273, an, 334, 36:3,as shown in Fig. 1. Acircular space D, adjoining thespace O and separated by one line, having a maximum diameter of four andfive-eigh ths inches, is divided into twelve equal parts to correspondwith the last-named divisions, each part to contain, respectively, thename of a month, abbreviated thus, Jan, Fell, Mala, Apia, Ma-y, Jun,JuL, Aug, Sep, Oct, Nov, Dec, as shown in Fig. 1, and within the samerespective spaces the respective serial numbers of the months, 1, 2, 3,t, 5, 6, 7, 8, 9, 10, 11, 12, as shown, and on the same imaginarycircular line the number 01 days belonging to each 01" the respectivemonths, 31, 2.8, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31, as shown inFig. 1. A circular space E, adjoining the space I) and separated by twoparallel lines, having a maximum diameter of iive and three-quarterinches, is divided into seven equal parts, each part to contain,respectively, the names of the successive days of the week, l\/l onda,'r, Tuesday, VVednes day, Tlhursday', Friday, Saturday, and Sunday,abbreviated thus, Mon, Tue, Wed, Thu, Fri., Sat, Sun., as shown inFig. 1. A circular space F, adjoining the space E and separated by oneline, having a maximum diameter of seven inches and divided, tocorrespond with the last divisions, into seven equal parts,

each part to contain, respectively, the figures representing all thedays of the month which will fall on the successive days of the week,respectively, as follows: 7, 14, 21, 28, 1, 8, 15, 22, 29, 2, 9, 16, 23,3O, 3, 10, 17, 24, 31, A, 11. 18, 25, 5, 12, 19,26, 6, 13, 20, 27, asshown in Fig. 1. A circular space G, adjoining the space F and separatedby two parallel lines, having a maximum diameter of seven andthree-quarter inches to contain the word Sundays at its base and therespective names of the twelve months abbreviated, with the respectivedates of each month which will fall on a Sunday following the same,thus, Jan. 6, 13, 20, 27, Feb. 3, 10, 17, 24:, Mar. 3, l0, 17, 2 1, 31,A r. 7, 11, 21, as, May 5, 12, 19, 26, Jun. 2, 9, 16, 23, 30, Jul. 7,14, 21, 28, Aug. 1, 11, 18, 25, "Sep. 1, 8, 15, 22, 29, Oct. 6, 13, 2O,27, NOV. 3, 10, 17, 24, Dec. 1, 8, 15, 22, 29, as shown in Fig. 1.

It will be observed that the various spaces allotted for the item ofinformation will admit the use of a variety and size of type calculatedto give the greatest prominence to the most important matters ofinterest.

Holidays may be designated, as ordinarily, by the representative figurebeing printed in red ink or by its having a red star or other characterprinted across it or a sign printed conjointly with it.

It will be observed that the entire composition of a printed sheet willform asymmetrical dial in appearance and is divided into four mainparts, respectively, by double parallel lines. Two of these parts aresubdivided into various arc-sections and comprehensively connected, asshown in Fig. 1.

The series of calendar-sheets it, Figs. 1 and 2, are backed with a stiffpiece of cardboard L and clamped firmly together with eyelets r, s, t,and 16 near each corner, as shown.

Fig. 2 shows the centrally-affixed stud m with a head a, the washer 0,the index-hand I, the front disk o, the calendar-sheets it, thecardboard backing L, the rear disk 3 and eyelets and t.

In permanently affixing the index-hand I, Fig. 2, the stud m is first tobe slipped through the metallic washer 0, then through the hole in thebutt-end of the index hand I, then through the front metallic disk 01,then through the centers of the calendar-sheets 72. and the cardboardbacking L, and, lastly, through the rear metallic disk ;1 after whichthe projecting end of the stud m is bent approximately at a right. angleand down against the rear disk y, as shown, so that the necessary amountof pressure is brought to bear against the surfaces of the butt-end ofthe index-hand I by being clamped between the washer 0 on one side andthe disk 21 on the other side, thus serving to hold it with reasonablefirmness in the various positions required.

small jagged portions of the same around the eyelets '2' s t a andobviously around and slightly beyond the edge of the metallic disk t,Fig. 2, whereby the circular elastic pad w, formed by the core centersof the calendar-sheets it, remains intact approximately Within thedotted lines It and Z and yields a constant pressure against the disk11, which will serve to hold the index-hand I in any position requiredwhether one or more of the calendar-sheets law have been torn away.

A knob may obviously be keyed to or form an integral part of theindex-hand I to facilitate the rotation and setting of the same.

The sheet of cardboard backing L may be of a size and shape to admit ofdisplaying upon one or more of its marginal sides advertisements,pictures, interesting printed matter, or other useful features.

Having described the composition of the January sheet, we will note thedifierences existing in the composition of eleven remaining sheets, asfollows: First, the February sheet has the dates 29, .30, 31 removedfrom their respective arc-sections in the circular space F, and theremaining dates 1, 8, 15, 22, 2, 9, 16, 23, anC 10, 17, 24 are spreadout in their respective arc-sections. All other dates in this circle areleft intact as they now are. Secondly, as the first day of February willfall on a Friday the entire circle E, composing the days of the Week,has been shifted so that the arc-section containing the letters Fri.adjoins and corresponds with the arc-section containing the dates 1, 8,15, 22. Thirdly, from the central space A the letters Jan. have beenremoved and Feb. substituted instead. Fourthly, the serial number of themonth 1 has been removed from the central space A and 2 substitutedinstead. ences in the composition of the February from the Januarysheet. Hence I deem it unnecessary to show more than the component partsof the January sheet by drawings.

March differs from the January sheet as follows: The letters Fri.areplaced relatively to designate that Friday will be the first day ofthe said month, and the central space has the number 3 in place of 1 andthe letters Mar. in place of Jan.

April differs from the January sheet as follows: The date 31 is removedfrom its arcsection and the dates 3, 10, 17, 2 1 are spread out in thesaid section. The letters Mon.

These are the only difien IIO are placed relatively to designate thatMonday will be the first day of the said month, and the central spacehas number t in place of l and the letters Apr. in place of Jan.

May differs from the January sheet as follows: The letters \Ved. areplaced relatively to designate that Wednesday will be the first day ofthe said month, and the central space has number 5 in place of l and theletters May in place of Jan.

June differs from the January sheet as fol lows: The date 31 is removedfrom its arcsection and the dates 3, 10, 17, 24: are spread out in thesaid section. The letters Sat. are placed relatively to designate thatSaturday will be the first day of the said month, and the central spacehas number 6 in place of 1 and the letters Jun. in place of Jan.

July differs from the January sheet as follows: The letters Men. areplaced relatively to designate that Monday will be the first day of thesaid month, and the central space has number 7 in place of 1 and theletters Jul. in place of Jan.

August differs from the January sheet as follows: The letters Thu. areplaced relatively to designate that Thursday will be the first day ofthe said month, and the central space has number 8 in place of 1 and theletters Aug. in place of Jan.

September differs from the January sheet as follows: The date 31 isremoved from its arc-section, and the dates 3, 10, 17, 24 are spread outin the said section. The letters Sun. are placed relatively to designatethat Sunday will be the first day of the said month, and the centralspace has number 9 in place of 1 and the letters Sep. in place of J an.

October differs from the January sheet as follows: The central space hasnumber 10 in place of 1 and the letters Oct. in place of Jan.

November differs from the January sheet as follows: The date 31 isremoved from its arc-section, and the dates 3, 10, 17, 24 are spread outin the said section. The letters Fri. are placed relatively to designatethat Friday will be the first day of the said month, and the centralspace has number 11 in place of 1 and the letters Nov. in place of Jan.

December differs from the January sheet as follows: The letters Sun. areplaced relatively to designate that Sunday will be the first day of thesaid month, and the central space has riumber 1 in place of 1 and theletters Dec. in place of Jan.

It will be evident that the changes required in the composition ofmatter for printing the several calendar-sheets are few and simple, forthe reason that about five-sixths of the entire matter composing theJanuary sheet, as

shown in Fig. .1, must always remain intact for repeated impressions inconjunction with the minor changes, as described.

The calendar-sheets for a leap-year will obviously require the followingchanges in their composition: The numbers now in the circle C forshowing the age of the year at the end of each month must all be removedfrom their respective arc sections excepting number 31R the Januarysection, and substituted, respectively, by numbers 60, 91, 121, 152,182, 213, 24: 1, 9.74, 305, 335, 366 for printing each of the twelvemonthly sheets. The name and numbers Feb. 28, now in one of thearc-sections of the circle D, must be made to read Feb. 2, 29101'printing each of the twelve monthly sheets. \V hen printing the Februarysheets, the date 29 must be left remaining in its respective arc-sectionof the circle F.

The entire composition of the sheets may optionally be printed in two ormore colors for the purpose of giving greater prominence to the mostimportant items of information. Forthis purpose i would suggest that allthe composition in the central space A and a single border-line beprinted in black, all the composition in the combined circular spaces B,C, and D and their straight and curved lines in red, all the compositionin the combined circular spaces E and F and their straight and curvedlines in black, and all the composition in the circular space Gr and itscurved lines in red.

By referring to the extreme outer circle of the Janpary sheet for 1901,which contains the abbreviated names of each successive month and thedates of their respective Sundays, it can readily be ascertained uponwhich day of the week the 16th day of May will fall. The inspection willdisclose the fact that the 12th day of May will fall on a Sunday, andconsequently the 16th will fall on a Thursday. in like manner, su'iposing that in the month ol December, 1001, we are inspecting theDecember sheet of this calendar and desire to know which day of the weekwas the 8th day of January, the inspection will show that the 6th day ofJanuary was Sunday, and consequently the 8th must have been Tuesday.Hence the composition in the circle G will readily serve to discover anypast or future day of the month, with its corresponding day of the week,in a current year.

An inspection of the circle B and the circle D will show, respectively,that the season Spring embraces March, April, and May. Summer embracesJune, July, and August. Autumn embraces September, ()0- tober, andNovember. Winter embraces December, January, and F ebruary.

An inspection of the circle (J shows the age of the year up to the endof each successive month in number of days.

From the foregoing description my invention, which is obviouslysusceptible of mamfold modifications.
